In high-risk industries such as oil & gas, chemical processing, and offshore platforms, explosive gas atmospheres pose significant safety challenges. According to the IEC 60079-10-1 standard, industrial sites are classified into Zone 0, Zone 1, and Zone 2 based on the frequency and duration of the presence of explosive gases. Each zone comes with distinct requirements for the design and construction of functional enclosures, and understanding these differences is critical for safety and regulatory compliance.
Zone 0: Continuous Explosive Atmospheres
Zone 0 is the most dangerous explosive atmosphere and usually refers to internal spaces such as fuel tanks or chemical reactors where explosive gas mixtures are present continuously or for long periods of time.
As a rule, the installation of any non-essential enclosures or electrical equipment in Zone 0 should be avoided.If necessary, only intrinsically safe (Ex ia) or encapsulated (Ex ma) equipment according to IEC 60079-11 is permitted.The system should have continuous gas monitoring capability and be able to trigger an automatic power-off or alarm mechanism when a set threshold is reached.This ensures reliable operation in extreme Zone 0 environments with complete protection against dust and prolonged submersion in water.
Zone 1: Occasional Explosive Atmospheres
Zone 1 is an area where an explosive atmosphere may occur during normal operation, such as an offshore drilling rig work area or an oil refinery pump room.The enclosure must be protected by one or more of the following methods: explosion-proof (Ex d), pressurised (Ex p) or combined (Ex db + Ex pb).The pressurised system must ensure that the pre-blowing volume is at least 5 times the internal volume of a typical gas (according to IEC 60079-2) or 10 times the internal volume of hydrogen.A pressure monitoring interlock must be installed to automatically shut down the system if the pressure falls below 50 Pa (typical threshold; actual values may depend on product specifications or project requirements).Depending on the environment in which the equipment is installed, the enclosure should have a protection rating of not less than IP54 (indoor) or IP65 (outdoor) to ensure that the dust and water resistance meets the requirements for use.A two-channel gas detector should be installed with an alarm threshold set between 10% and 25% of the LEL (lower explosive limit).Materials must be explosion-proof, anti-static and corrosion-resistant.
Zone 2: Rare and Abnormal Explosive Atmospheres
Zone 2 areas experience explosive gas atmospheres only in abnormal conditions and for short durations, such as gas station ventilation zones or transition areas adjacent to Zone 1. Allowed equipment types include increased safety (Ex e), non-sparking (Ex nA), restricted breathing (Ex nR), and simplified pressurized enclosures (Ex pz). Even simplified systems must ensure a 5x air volume purge before energization. For outdoor enclosures, materials such as 316L stainless steel is recommended, with steel containers having a minimum thickness of 3 mm and GRP containers a minimum thickness of 8 mm（These thicknesses are based on industry best practices or product-specific standards, not on IEC mandates.）.
Conclusion
All explosion-proof container designs must strictly follow relevant standards, including IEC 60079, ATEX, and GB 3836. A few critical points to note: The commonly used designation “Ex de” is non-standard. The correct classification is “Ex db eb,” indicating a compound flameproof and increased safety solution. Pressurized containers (Ex p) are not permitted in Zone 0 and are only applicable in Zone 1 and Zone 2.
Each hazardous zone imposes increasing or decreasing demands on functional container design. Zone 0 allows only intrinsically safe or encapsulated equipment, Zone 1 requires multi-layered explosion protection strategies, and Zone 2 allows simplified protections but still requires adherence to core safety standards. By aligning design and manufacturing with the appropriate zone classification and international standards, equipment safety and operational integrity can be fully assured in explosive gas environments.

As global energy demand continues to rise and renewable energy adoption accelerates, energy storage technologies have become crucial to the success of the energy transition. Among these technologies, energy storage containers have emerged as a versatile and modular solution, offering flexibility in deployment and scalability across various applications—such as grid balancing, distributed generation, and emergency power supply.
1. Material Selection
The choice of materials directly impacts the container’s performance, reliability, and overall cost-effectiveness. Common materials used in the industry include:
1.1 Weathering steel(Corten steel)
Currently, weathering steel is a widely used structural material for energy storage containers.It has good mechanical strength, welding performance and cost advantages, and is suitable for mass production and complex structure manufacturing.Weathering steel can also form a stable corrosion protection layer on the surface, which improves its corrosion resistance and prolongs its service life.Compared to stainless steel, this type of steel ensures structural strength while significantly reducing material cost and weight, which is a good balance between performance and economy.
1.2 High-Strength Composites
High-strength composite materials have gained popularity for their lightweight, high durability, and abrasion resistance. These materials allow for optimized structural dimensions, making containers easier to install and transport, while maintaining reliability and strength.
2. Structural Design
A well-engineered structure is critical to ensuring safety, functionality, and efficiency. Key areas of structural design include:
2.1 Energy Storage System Configuration
The storage system is the core of the container. Design considerations should include battery capacity, voltage range, and cycle life, with a focus on maximizing energy storage efficiency and system longevity.
2.2 Thermal Management
Effective thermal management ensures optimal battery performance and extends lifespan. Designers must consider heating efficiency, temperature control, and energy-saving strategies. Forced air cooling or liquid cooling systems are commonly used to regulate internal temperatures.
2.3 Ventilation
Proper airflow is essential to maintain a safe and stable internal environment. Ventilation design should take into account air intake volume, humidity control, and temperature distribution to ensure the container remains within operational limits.To avoid the build-up of gases (e.g. thermal runaway gases), the installation of a gas venting and detection system should be considered.
2.4 Interface Design
Interfaces affect installation, commissioning, and overall user experience. Consideration should be given to the number, type, and placement of AC/DC and communication ports to enhance system integration and ease of maintenance.
3. Safety Performance
Safety is a core element in the design of energy storage vessels and is directly related to the reliability of equipment operation and personnel safety.The following are the key safety performance points:
3.1 Fire safety
The fireproof design should comply with international safety standards, such as UL 94, UL 9540A, IEC 62619 and so on.The structure of the container should be made of materials with high flame retardant rating and equipped with automatic fire extinguishing system, such as aerosol, dry powder or water mist system, if necessary.At the same time, exhaust channels should be reserved to cope with the release of gases after thermal runaway of the battery to reduce the risk of explosion.
3.2 Electrical Safety
The electrical system should be equipped with a battery management system (BMS) and an energy management system (EMS) to realise real-time monitoring and protection against over-charging, over-discharging, short-circuiting, over-temperature and other conditions.The system should meet IEC 62933, GB/T 36276 and other safety standards for energy storage systems to ensure that the power can be cut off quickly in case of failure and protect the equipment from further damage.
3.3 Moisture protection and sealing
Humid environment will cause corrosion and insulation risk to the battery performance and electrical components, so the container should have good sealing, the recommended protection level is not less than IP54 (indoor) or IP65 (outdoor).Waterproof seals, moisture-proof coatings and dehumidification modules are used to effectively control the internal humidity and ensure the long-term stable operation of the system.
3.4 Personnel and Operation and Maintenance Safety
The design should fully consider the operation safety of maintenance personnel.The container should be equipped with obvious safety warning signs, emergency stop switches, and enough space reserved for access.At the same time, in order to adapt to the trend of intelligence, it is evolving to support remote monitoring, abnormal alarm and remote power failure, which will help to respond quickly in unexpected situations.The structure and electrical layout of the vessel should comply with IEC 60204, OSHA, GB 50898 and other ergonomic and operational safety standards.
4. Conclusion
The design of energy storage containers involves an integrated approach across material selection, structural integrity, and comprehensive safety measures. Choosing the right materials is foundational to performance and cost-efficiency. Robust structural and thermal designs enhance operational stability, while meticulous attention to safety ensures protection for both equipment and personnel.
Looking ahead, the future of energy storage containers lies in intelligent, modular, and standardized solutions. Intelligence will enhance real-time monitoring and predictive maintenance, modularity will enable flexible deployment and scalability, and standardization will reduce costs and accelerate adoption.
As a cornerstone of the sustainable energy ecosystem, energy storage containers will continue to play a vital role in accelerating the global transition to clean, reliable, and resilient energy systems.
